Question

我已经通过互联网搜索解决了这个问题，但我无法找到解决方案。同步我的项目后，gradle运行时没有任何错误，但是当我打开build.gradle文件时，它通过在build.gradle（app）页面上加下划线compile 'com.android.support:appcompat-v7:25.3.1'来显示错误。当我检查更多信息时，它显示了这一点。

这是我的完整gradle文件：

apply plugin: 'com.android.application'

android {

    dexOptions {
        jumboMode = true
    }

    signingConfigs {
        config {
            keyAlias 'Lagchat'
            keyPassword 'HomeAlone'
            storeFile file('C:/Users/WESLEY/Desktop/APKBuild/android.jks')
            storePassword 'HomeAlone'
        }
    }

}
apply plugin: 'com.google.gms.google-services'

这是我对build.gradle（项目）的完整文件

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        jcenter()
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.3.3'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
        classpath 'com.google.gms:google-services:3.0.0'
    }
}

allprojects {
    repositories {
        jcenter()
        maven {
            url "https://maven.google.com"
        }
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

注意事项：我之前使用此compileSdkVersion 25 buildToolsVersion '25.0.3'之前将其更改为26和26.0.1，因为我在同步gradle时收到此错误Error:(15, 21) No resource found that matches the given name: attr 'android:keyboardNavigationCluster'.。

我该怎么做才能使这个项目运行没有任何错误。显然，即使在成功构建了gradle之后，也停止在build.gradle（app）上显示错误。

正如您所面临的错误所说

所有com.android.support库必须使用相同的版本规范

但是你有很多这个小组的模块提到了不同的版本。

您有firebase的依赖项，如果您运行gradle app:dependencies，则可以看到以下依赖项树

+--- com.google.firebase:firebase-core:11.0.4
|    \--- com.google.firebase:firebase-analytics:[11.0.4] -> 11.0.4
|         +--- com.google.firebase:firebase-analytics-impl:[11.0.4] -> 11.0.4
|         |    +--- com.google.android.gms:play-services-basement:[11.0.4] -> 11.0.4
|         |    |    \--- com.android.support:support-v4:25.2.0 -> 27.0.1
|         |    |         +--- com.android.support:support-compat:27.0.1
|         |    |         |    +--- com.android.support:support-annotations:27.0.1

因此firebase引用com.android.support版本的27.0.1库

因此，您需要更新您的依赖项以协调您的项目。

然后改变：

compile 'com.android.support:appcompat-v7:26.0.1'
compile 'com.android.support:support-v4:26.0.1'
compile 'com.android.support:design:26.0.1'

与

compile 'com.android.support:appcompat-v7:27.0.1'
compile 'com.android.support:support-v4:27.0.1'
compile 'com.android.support:design:27.0.1'

之后，您还需要更新compileSdkVersion

更改

compileSdkVersion 26

带

compileSdkVersion 27

最后

+--- com.afollestad.material-dialogs:core:0.9.4.5
|    +--- com.android.support:support-v13:25.3.1
|    |    +--- com.android.support:support-annotations:25.3.1 -> 27.0.1

support-v13引用版本25.3.1

所以在你的依赖项中添加一行

compile 'com.android.support:support-v13:27.0.1'

因此，gradle的解决策略可以选择更高版本

RECAP ，您的依赖项应该以这种方式更改：

dependencies {
    ...
    compile 'com.google.firebase:firebase-core:11.0.4'
    compile 'com.google.firebase:firebase-core:11.0.4'
    compile 'com.android.support:appcompat-v7:27.0.1'
    compile 'com.android.support:support-v13:27.0.1'
    compile 'com.github.paolorotolo:appintro:4.1.0'
    compile 'com.android.support:support-v4:27.0.1'
    compile 'com.android.support:design:27.0.1'
    compile 'com.google.firebase:firebase-auth:11.0.4'
    compile 'com.google.firebase:firebase-config:11.0.4'
    compile 'com.google.firebase:firebase-database:11.0.4'
    compile 'com.google.firebase:firebase-messaging:11.0.4'
    compile 'com.google.firebase:firebase-storage:11.0.4'
    compile 'com.google.firebase:firebase-invites:11.0.4'
    compile 'com.google.firebase:firebase-crash:11.0.4'
    compile 'com.google.firebase:firebase-appindexing:11.0.4'
    compile 'com.google.firebase:firebase-ads:11.0.4'
    ...
}

别忘了compileSdkVersion 27

Gradle构建成功没有错误但仍显示build.gradle（app）页面上的错误
